Specification of Letters Patent.

Patented July 17, 1906.

Application filed November 10, 1904. Serial No. 232,147.

T0 all 1117141171, it may concern.-

Be it known that we, WILLIAM B. COATS and BENJAMIN L. COATS, citizens ofthe United States, residing at Pontiac, county of Oakland, State ofMichi an, have invented a certain new and useful chines for ExhibitingCards; and I declare the followingto be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

This invention relates to card-exhibitors. It has for its object animproved machine for automatically exhibitin a sequence of cards whichare transferred from one part of the machine to another and retained atan exhibition-place during intermissions of the transfer.

In the drawings, Figure 1 is a side elevation of the machine with one ofthe sides of the casing removed. Fig. 2 is a front elevation showin thetop of the machine with a card on exhi ition. Fig. 3 is a detail of partof the transfer device.

1' indicates a case in which is mounted a clockwork-motor 2, whichpropels the moving parts employed to transfer the cards.

In the casing above the motor are two sets of'horizontal parallel bars28 29, provided with notches on their upper edges. The upper pair ofbars 29 act in conjunction with a pair of movable serrated bars 4, whichare united by levers 6 and 7 to a pair of horizontal bars 5, alsoserrated and located directly below the bars 4:. The levers 6 and 7 arepivotally connected to levers 8 and 9, which are themselves pivoted atpoints 8 and 9 to the frame. The inner ends of the levers 8 and 9 arelinked to a vertically-movable rod 10, on the lower end of which is afoot 10, that engages under antifriction-roller 11 on an arm extendingbeyond the periphery of a wheel 12, which is driven by the spring-motor.

The part of the machine thus far described serves to periodically liftthe two serrated frames 4 and 5. These are also periodicallyreciprocated by a lever 13, which also receives its impulses from thewheel 12, which for that purpose is provided with an antifriction-roller14 on its periphery that engages a swinging but spring-held foot 15,pivotally connected to the lever 13. The

Improvement in Maswung in one direction by the contact be tween the foot15 and the antifriction-roller 14. It is swung in the reverse directionby the antifriction-roller 14:, which at a later period in the rotationof the wheel 12 engages against the foot 16 and swings the arm 13 in adirection reverse to the motion previously given to it. This movementproduces ahorizontal reciprocating movement and the previous movementproduced-a vertical reciprocating movement. 1

Cards are lifted from the lower set of bars to the upper set of bars byan arm 17, pivoted to a lever 18, pivoted to the frame of the case at37, which is actuated by the antifriction-roller 11, that engagesagainst the end 18 of the lever 18 and swings the pivoted end and thearm 17 upward. The end 17 of this arm is pivoted to a forlcterminatedrod 17*, which engages in guides 17 on the casing and reciprocatesvertically from bars 28 to bars 29. It will be noted that the upper orleft-hand end of the lever 18 is terminated by a piece whose shape, asshown in Fig. 1, re-

, sembles a reversed interrogation-point. This bridges over the distancebetween the end 18 and the adjacent end of the link 18 and at the sametime facilitates its passage during an actuating stroke past the pivotedsupport of the foot 10*, which when the machine is at rest is quiteclose to the link 18*. Although our experience leads us to believe thatthis form of bridging member is the most desirable, especially in caseof any unintended, irregular, or waving movement of the adjacent parts,we see no objection to the use of a straight strip or connecting-pieceas a substitute for the form shown.

The cards are mounted on rods or wires which project beyond the ends ofthe cards and constitute supports for the cards on the bars 28 and 29.The projections 19 and 19 rest in notches 2 and 3 on the bars 28 and 29,which are fixed to the frame. The projecting ends 19 19 are periodicallylifted out of the notches by the frames 4 and 5, which vertically risefor that purpose, and are transferred to the next succeeding notch bythe horizontal reciprocation of the frames 4 and 5, after which theframes 4 and 5 drop and return to the position they had before rising.The last cardin the series at the end 20 drops from the bar 29 along theincline 29 into a seat I) at the upper end of thevertically-reciprocating transfer-rods 2 which reciprocate lever 13 ispivoted to the frame at,13 and is 1 through guides 19*.

The transfer-rod is actuated by lever 18, to which it is connected bylink 18'.

A pair of swinging plates 22 is pivoted at each end of the machine at 38and 39, one 011 each side of the casing. These plates normally hang eachwith its outer edge (that toward one of the inspection-apertures 25 and26) contacting the glazing or the end of the case. As a card is beinglifted from the delivery end of the bar 28 to the receiving end of thebar 29 by the fork-terminated rod 17' these outer edges of the plates 22engage against the outer ends of the wire 19 19, which are forced bythem into close engagement with the glazing and end of the casing, andthus held uniformly in position. Similarly, the pair of plates at thedelivery end of the bar 29 by engagement against the extreme outer endsof the wires guide a card in its descent, so that it does not fallslantwise and clog the passageway.

The last card of the lower series at the end 23 is lifted by the forkedend 17' of the rod 17', with the projecting wires engaging in the forks.During the upward travel of the card the ends of the wires pass betweenthe swing ing plates 22 and the case, and the rod 17 continues to riseuntil the ends are carried above the incline 24, over which they thenengage, after which the arm 17 drops and the card slips down the incline2-1 into the notch 3 The weight 17 near the lower end of the arm 17causes these parts to fall into position for the next stroke with aquick sharp movement.

During the early part of the upwarclmovement of the arm 17 and thefork-terminated rod 17 on which the card is suspended, the upperserrated bar 4 has beenmoving to the left, as seen in Fig.1, inadvancing thecards toward the delivery end of the notched bar 29, thusleaving a considerable space at the right-hand end, past which the cardthat is being lifted is traveling. When, however, the upper limit oftravel is reached and the wire 19 is held suspended above the incline24, the drop of the bar 17, which is made possible by the action of theclockwork, which is located at the base of the machine and which isaccelerated by the presence of the weight 17 on the bar, is so sudden asto jar the wire of the card from its position in the forked terminal,and it cannot fall elsewhere than on the incline 24,for the reason thatmeantime the serrated bar 4 has been moved to its extreme rightposition, as shown in Fig. 1, so that the space between its end and theadjacent poi tion of the case does not permit thewire carrying the cardto slip down between them.

A constant rotary movement is given to the wheel 12 by a cord 12which'is driven by the spring-motor. The ends of the case are glazed at25 and 26, and during the revolution of the wheel 12 there .is a periodof rest in the movement of the reciprocating parts that leaves the cardsunder the glazing 25 and 26 for inspection for a period of timedetermined by the rate of motor speed. Both sides of the card should beprovided with matter to be exhibited and the capacity of the machine isindefinite.

What we claim is 1. In a card exhibitor, a plurality of notched barsalong which cards may travel, means for simultaneously moving the cards,those on one bar in theopposite directionto those on the other bar, andvertically-reciprocating means adjacent to the delivery end of one barand to the receiving-end of the other bar whereby a card may be carriedfrom said delivery end to said receiving end, substantially asdescribed.

2. In a cardexhibitor, in combination with means for holding cardsspaced, a movable actuating device adapted to shift cards along thesame, and means reciprocating vertically at the end of said card-holdingmeans for carrying a cardfrom the delivery end of one of said spacingmeans to the receiving end of the other, substantially as described.

3. In a card exhibitor, in combination with horizontallydisposed notchedbars,

cards with wires projecting therefrom adapted to rest on saidnotchedbars, a transferring device adapted to receive the card and'itswire, and transfer it to a similar set of notched bars, a notched plateand means to actuate the same to engage the said wires and: shift eachfrom the notch in which it rests to a succeeding notch and to shift thecard and its holding-wire at the ends of the said bars into atransferring device,- located adjacent to the first set of notchedbars,substantially as described.

In testimony whereof we sign this specification in the presence of twowitnesses;
